The crowd of 32,534 was stunned as the Eagles extended their unbeaten run at Adelaide Oval over the Power at Adelaide to five games – including last year's epic elimination final that Shuey won off his boot in extra-time.

McGovern's match-winning goal was the first time the Eagles led all game.

They trailed by 10 points with less than a minute on the clock before Mark LeCras kicked a goal with 45 seconds left to give them a sniff.

The Eagles (15-5) remain second on the ladder and are eight points clear of third-placed Hawthorn with two games remaining.

Star ruckman Paddy Ryder left the game with a re-occurrence of a hip flexor injury, half-back flanker Dan Houston was taken off in a medicab after a strong collision with Eagles midfielder Brendon Ah Chee and key forward Charlie Dixon hobbled off with an ankle injury.

Port Adelaide: It was a horror night for the Power as they finished with 19 fit players. The worst is key forward Charlie Dixon, who is out for the rest of the season with a serious ankle injury. "Dixon won't play again this year, he's got a badly sprained, possibly broken ankle," Power coach Ken Hinkley said. Dixon hit the ground awkwardly in a marking contest with Tom Barrass in the third quarter. Star ruckman Paddy Ryder left the game in the third quarter with a re-occurrence of his hip flexor injury. "Ryder, aggravated hip flexor, he's still some chance (for next week's game) because we took the cautious approach where we're at in the season," Hinkley said. Defender Dan Houston was taken off in a medicab after a heavy collision with Brendon Ah Chee in the third quarter. "He's had some precautionary X-rays and stuff, but I think he'll be fine," Hinkley said.

West Coast: Nathan Vardy and Liam Ryan collided early in the second term. Vardy had his left knee looked at by the medical staff. Ryan was helped off the ground with a cork to his right thigh, but returned to play and took a mark of the year contender in the last quarter. Vardy went back on the ground to start the third term and finished the game.

NEXT UPThe Eagles have an eight-day break before another huge challenge when they host Melbourne at Optus Stadium next Sunday. The injury-depleted Power will be outsiders to beat Collingwood at the MCG next Saturday. However, the Power have won their past four against the Magpies.
